    • In the era of interconnection of all things, the demand for computing power and punctuality of massive terminal devices is increasing, which effectively promotes the development of edge computing. However, the disadvantages of limited computing power resources and narrow computing power coverage scene of edge computing make it difficult to analyze and process the global data and form a long-term storage of data. Cloud side collaboration gives full play to the advantages of cloud computing and edge computing, realizes the collaboration of cloud side nodes in resources, data, business and other fields, and can better meet the computing power needs of the Internet of things era. Through the analysis of the cloud edge collaborative construction scheme of large central enterprises, this paper summarizes the technical highlights and reference significance of cloud edge collaborative construction of large central enterprises, which will provide important support for the practice of cloud edge collaborative technology of Chinese enterprises.

    • With the continuous expansion of computing power demand scenario, the form of computing power facilities and computing power supply has changed. The trend of network cloud transformation is obvious. The deep integration of cloud networks can quickly realize the interconnection between clouds and users, and the efficiency of cloud services is improved. In recent years, ubiquitous terminal IOT scenarios become increasingly rich, users need ubiquitous access, on-demand, customized, efficient and convenient computing services. The computing network collaboration system develops rapidly, and the popularity of computing network is increases. The computing power network improves the quality and efficiency of computing power service through technical means such as network cloud and pool transformation, unified identification of computing network resources, intelligent arrangement of computing network resources, data minimalist forwarding and so on. The construction of computing network collaboration system needs the coordination and linkage of data center and network facilities. This paper discusses the impact of computing network collaboration on computing power industry, and gives development suggestions.

    • As the power density of data centers increases, heat dissipation becomes a major challenge to ensure the smooth running of devices and promote green and healthy development of data centers. Liquid cooling technology can effectively solve the problems of high-density deployment and partial overheating of the machine room, among which immersion liquid cooling technology has been widely considered because of its outstanding heat dissipation and energy saving advantages. In this paper, two typical immersion liquid cooling modes of single phase and phase change are introduced, the key issues of the coolant under the two modes are discussed, also the performance and application differences of hydrocarbon, organosilicon and fluorocarbon compounds, as well as their impacts on safety and environment are emphatically analyzed.
